Specification of Letters Patent.

Application filed September 7, 1915. Serial No. 49,191.

To all whom it may concern Be it known that 1, ALBERT C. BARTELT, a citizen of the United States, residing at 'Medford, county of Taylor, and State of Wisconsin, have invented new and useful 1m rovements in Motor-Driven Vehicles, of which the following is a specification.

My invention relates to improvements in motor driven vehicles.

. The object or my invention is to so modify the .movements, particularly the vertical movements, transmitted to the main frame through the vehicle wheels when traveling over rough or uneven roads, as to relieve the main frame, the supporting sprin the enine, and the passengers from s ocks and golts to a large extent, and also to allow the wheels to lift and pass over obstructions more easily than in an ordinary vehicle.

A further object of my invention is to provide a more adequate and flexible suport for the main frame, to extend the wheel use and at the same time facilitate short turning movements, and to properly distribute and equalize the load upon six wheels instead of four.

' In the drawings- Figure 1 is a plan view of a motor driven vehicle embodying my invention, with the body removed.

Fig. 2 is a side elevation of the same.

Fig. 3 is a sectional view, drawn on line m-a: of Fig. 2.

Like parts are identified by the same reference haracters throughout the several views.

The front and rear axles 1 and 2 are provided with steering wheels 3 and 4, respectively. Substantially midway between the front and rear axle, is a hollow supporting axle 7 provided with traction wheels 8. Loose collars 9 on the axle 7 near its respective ends, are each connected with the front and rear axles by link rods 10 and 11.

The main frame 12 is supported by springs 13 from the linlr rods 10 and 11 respectivcly, by means of links 16 and trans- .verse rocking arms or shafts 17, the latter being journaled in supporting bearin memhers 19 mounted on the link rods 10 or 11). i The load carried by the main frame including its own weight, is therefore supported by the link rods at points intermediateof- I the middle axle and the respective end axles The en ine 22 is mounted on the main frame an its power is transmitted to the traction wheels 8 through the hollow axle 7 in the usual manner. The latter' is connected to the main frame by strut rods 23', f. 24 is a differential gear casing. The main frame is arched at 25 over the axle 7, where- 1 by the latter may move vertically to any ordinary extent without striking'the. frame.

Stcering movements. are transmitted to ;the rear wheels through link rods 28 .and29 and an intermediate oscillatory yoke 30 pivoted to the main frame at 31.

The links 16 permit limited relativemove ments of the main frame laterall and the rock arms or shafts 17 permit limited lon' tudinal movements, these movements, or t e pressures which reduce them,be1ng in turn absorbed or distributed by the springs.' The subframe provided by the axles and link rodsis therefore very flexible, and each,

wheel can conform to the roadway without" setting up strains.

While I have referred to the connection 1 for the main frame with the rods 10 and 11 as distributing and equalizing the'load, I do not mean thereby that an equal portion of the load is carried by all of the axles, since it is obvious that in the construction illus trated one-half of the total load is carried. 1

by the axle 7 and-the traction wheels. The

link rods and the rocker bearing and link connections of the main frame therewith,

are effective however in distributing-or.

diatc axle, a spring supported main frame arched over the intermediate axle, link con-j ncctions between the intermediate axle and the front and rear axles respetively,

having front and j rear axles, the combination of on interme' axles connecting the front and rear wheels,

with their respective supporting axles,alnd

a steering head operatively connected with all of the stub axles.
